I did he AV stuff. Electrum not listed as a threat. And I switched the AV protection off and started Electrum, and still not connected.

But I found the log files and inhem is this:
interface.[ex.btcmp.com:50002] | disconnecting due to: ErrorGettingSSLCertFromServer(ConnectError(ConnectionRefusedError(22, 'The remote computer refused the network connection', None, 1225, None)))

So it eems the remote servers listed by Electrum are refusing to connect to my computer.
Do I need to have my Electrum verified or authorised? By using signatures?
